For the quarter, Baidu posted revenue of $677.1 million up 75% from a year ago, and about in line with the Street consensus at $677.4 million. The company posted non-GAAP profits of 87 cents a share, ahead of the Street at 84 cents.

For Q2, the company sees revenues of $847.2 million to $867 million; that would put the mid-point of the range a hair below the Street consensus. The forecast would mean top line growth in the 56.2% to 59.9% range.

"We've started the year with solid financial results and steady business progress," s CEO Robin Li said in a statement. "Although this is usually a seasonally slow quarter, our effective sales and marketing efforts enabled us to expand our SME customer base significantly."
